A window curtain pull cord concentrator safety device of the present invention provides a concentrator device which enables the gathering together of the free ends of a plurality of pull cords of a window curtain set, and enables complete transmission of a pulling force in an emergency. And basically comprises a drag cup, an inner bottom of a concave cavity of which is provided with a through hole enabling a wire hoop body coupled to a pulling member to penetrate therethrough. The wire hoop body is located in the interior of the drag cup, and displacement of an inner loop side of the wire hoop body relative to the drag cup is used to determine whether the free ends of the pull cords are radially restrained, thereby enabling complete relay transmission of the pulling force. In an emergency, the pull cords are rapidly released, thereby achieving instantaneous prompt safety effectiveness. |
